PROBLEM TO BE SOLVED: To allow a user to easily grasp the spatial position relation between an area of concern and structures around it while suppressing the radiation exposure dose of a subject.SOLUTION: A radiation image photographing system includes a radiation image photographing part that photographs a radiation image shown by a radiation transmitting through a subject. It is configured to set a moving area in the subject as an area of concern and to execute still image photographing executed by irradiating a radiation to a photographing target area including the area of concern (S202) and moving image photographing executed by irradiating a radiation only to the area of concern (S204-S212). It is configured to control such that, when the position of the area of concern approaches the edge of the photographing target area during moving image photographing after the still image photographing, the still image photographing is executed by moving the position of the photographing target area so that the area of concern is moved away from the edge in the photographing target area (S218-S220). It is configured to display the moving image of the area of concern, obtained by the moving image photographing, on the still image of the photographing target area, obtained by the still image photographing, by superimposing the moving image on the corresponding position.COPYRIGHT: (C)2013,JPO&INPIT【課題】被検者の被曝量を抑制しつつ、関心領域とその周辺の構造物との空間的な位置関係を容易に把握することができる。【解決手段】被検者を透過した放射線により示される放射線画像を撮影する放射線画像撮影部を備え、被検者における移動する領域を関心領域として、当該関心領域を含む撮影対象領域に対して放射線を照射して行う静止画撮影(S202)、及び当該関心領域のみに放射線を照射して行う動画撮影(S204乃至S212)が行われると共に、静止画撮影後の動画撮影中に関心領域の位置が当該撮影対象領域の端部に近づいた場合に、関心領域が撮影対象領域内で端部とは離れるように撮影対象領域の位置を移動させて静止画撮影が行われるように制御し(S218乃至S220)、静止画撮影によって得られた撮影対象領域の静止画像に、動画撮影によって得られた関心領域の動画像を対応する位置に重ねて表示する。【選択図】図10
